Asheet of bcc iron 4.0-mm thick was exposed to a carburizing atmosphere on one side and a decarburizing atmosphere on the other side at 725°c. after having reached steady state, the iron was quickly cooled to room temperature. the carbon concentrations at the two surfaces were determined to be 0.011 and 0.0069 wt%. calculate the diffusion coefficient if the diffusion flux is 2.9 × 10-8 kg/m2-s, given that the densities of carbon and iron are 2.25 and 7.87 g/cm3, respectively
